Answer:

F_m= 8.28 \times 10^{-16} N

Explanation:

The magnitude of the force is F_m=evB\sin\theta\\\implies F_m=1.602 \times 10^{-19}\times 300\times 19\times\sin 65^0= 8.28 \times 10^{-16} N

A rigid, nonconducting tank with a volume of 4 m3 is divided into two unequal parts by a thin membrane. One side of the membrane
kondor19780726 [428]

The final temperature of the system will be equal to the initial temperature, and which is 373K. The work done by the system is 409.8R Joules.

To find the answer, we need to know about the thermodynamic processes.

<h3>How to find the final temperature of the gas?</h3>
  • Any processes which produce change in the thermodynamic coordinates of a system is called thermodynamic processes.
  • In the question, it is given that, the tank is rigid and non-conducting, thus, dQ=0.
  • The membrane is raptured without applying any external force, thus, dW=0.
  • We have the first law of thermodynamic expression as,

                                dU=dQ-dW

  • Here it is zero.

                                  dU=0,

  • As we know that,

                             dU=C_pdT=0\\\\thus,  dT=0\\\\or , T=constant\\\\i.e, T_1=T_2

  • Thus, the final temperature of the system will be equal to the initial temperature,

                          T_1=T_2=100^0C=373K

<h3>How much work is done?</h3>
  • We found that the process is isothermal,
  • Thus, the work done will be,

                               W=RT*ln(\frac{V_2}{V_1} )=373R*ln(\frac{4}{\frac{4}{3} })\\ \\W=409.8R J

Where, R is the universal gas constant.

<h3>What is a reversible process?</h3>
  • Any process which can be made to proceed in the reverse direction is called reversible process.
  • During which, the system passes through exactly the same states as in the direct process.

Thus, we can conclude that, the final temperature of the system will be equal to the initial temperature, and which is 373K. The work done by the system is 409.8R Joules.

The third-order bright fringe of 610-nm light is observed at an angle of 31° when the light falls on two narrow slits. How far a
Anna11 [10]

Answer:

The distance between the slits is 3.55 μm

Explanation:

Given that,

Order number = 3

Wave length = 610 nm

Angle = 31°

We need to calculate the distance between the slits

Using formula of distance of slit

d\sin\theta=n\lambda

d=\dfrac{n\lambda}{\sin\theta}

Where, n = order number

\lambda= wavelength

Put the value into the formula

d=\dfrac{3\times610\times10^{-9}}{\sin31}

d=3.55\times10^{-6}\ m

d= 3.55\ \mu m

Hence, The distance between the slits is 3.55 μm.

if a ball is accelerated downward at 9.8m/s, by how many meters per second does the object's velocity change every second?
Stella [2.4K]

The velocity will change (increase) by 9.8 m/s every second.

Why?

Since the ball is accelerated downward at 9.8\frac{m}{s^{2} } we can see that the ball is on "free fall". It means that the wall was dropped with no initial speed.

Now, if we want to know by how many meters per second does the object's velocity change every second, we need to understand the units of the acceleration. Let's write the equation of acceleration for better understanding.

Acceleration=\frac{ChangeInVelocity(\frac{m}{s})}{time(s)}\\\\Acceleration=\frac{\frac{m}{s} }{s}=\frac{m}{s^{2} }

So, from the equation we can see that the acceleration is changing the velocity every second.

Hence, if an object has the given acceleration (acceleration due to gravity, 9.8m/s2), it means that its speed will change (increase) by 9.8m/s every second.

Have a nice day!
